Filter by:The purpose of this study is to determine whether treatment outcome for subjects dependent on prescription opioid analgesics can be improved by adding individual drug counseling to the prescription of buprenorphine/naloxone with standard medical management. This will be examined during: a) an initial four-week treatment with taper; b) a 12-week stabilization treatment for those who do not respond successfully to the initial treatment; and c) a long-term follow-up assessment at 1.5 years, 2.5 years, and 3.5 years after treatment.
Opioids are one of the most commonly abused drugs among individuals who seek treatment for drug abuse. Thus, it is necessary to develop new treatments for opioid addiction. The purpose of this trial is determine whether tramadol is effective in treating opioid dependent individuals.
Background: - Though the drug buprenorphine effectively treats dependence on opioids like heroin, some abstinent patients relapse to use during treatment. This relapse may be triggered by stress or stressful situations, and buprenorphine probably has no specific protective effect in these situations. Buprenorphine probably also has no specific effect on relapse to cocaine use. - Research has shown that clonidine, a drug originally prescribed to treat high blood pressure and some symptoms of opioid withdrawal, can help block stress-induced relapse to heroin and cocaine seeking in rats. Researchers are interested in studying whether a combination of clonidine and buprenorphine may be more effective in preventing drug relapse than administering one of the medications alone. Objectives: - To determine whether clonidine, given to abstinent patients maintained on buprenorphine, is more effective than placebo in preventing relapse to heroin or cocaine use. Eligibility: - Individuals between 18 and 50 years of age who are current cocaine or heroin users seeking treatment. Design: - The study will last up to 36 weeks, with four phases of treatment and a follow-up evaluation. Three times a week, participants will be asked to report illicit drug use and provide urine and breath samples. Throughout the study, participants will receive individual counseling in weekly 40 60 minute sessions. Other samples and tests will be scheduled as required by the study researchers. - Patients will be stabilized on daily buprenorphine over the first 14 days of the study. - Weeks 1 8: Participants will receive vouchers for regular substance-free urine samples. Those who successfully complete this phase will continue to the next part of the study. - Weeks 7 9: Participants will receive either clonidine or placebo along with the buprenorphine. The dose of clonidine will be stabilized during this time. - Weeks 9 22: Participants will continue to receive either clonidine or placebo along with the buprenorphine. During this part of the study, participants will keep electronic diaries to record drug use or craving and to record data on mood, stress levels, and activity. - Weeks 23 28: Participants will stop taking the clonidine or placebo, but will continue the buprenorphine treatment. Participants will continue to keep electronic diaries. - Weeks 29 36: Participants will have the choice of transferring to a community clinic transfer or gradually reducing doses of buprenorphine to end the study. - Participants will return for a follow-up visit and urine sample 6 months after the end of the study.
Background: - The treatment of addiction often hinges on preventing relapse into drug-using behaviors, which occurs at high rates even after prolonged abstinence. Research has shown that constant reporting through personal data-collection devices, such as electronic diaries, can help prevent relapse and reinforce abstinence. This constant reporting is known as Ecological Momentary Assessment (EMA). - The researchers here at NIDA have already completed two major arms of the study, focusing on patterns of craving and drug use during methadone maintenance, and on whether electronic diaries could help remind outpatients to complete treatment tasks. An ongoing arm of the study is examining connections among drug craving/use, stress, and geographical location. Objective: - To investigate the role of stress associated with geographical location in drug craving and use. Eligibility: - Individuals between 18 and 65 years of age or older who are dependent on opioids (cocaine and/or heroin). Design: - The study will last 28 weeks. After the initial screening, participants will receive daily methadone and weekly drug counseling sessions that will continue throughout the study. - After 3 weeks of methadone treatment, participants will have 15 weeks of EMA in which they will record both event-triggered cravings and daily responses (3 per day). EMA will consist of event-triggered recordings (initiated by participants whenever they use heroin or cocaine, or whenever they feel an urge to do so) and random-signal-triggered recordings (3 per day). During EMA, participants will begin a voucher-based program to encourage abstinence from heroin and cocaine. - Participants will also carry global positioning system (GPS) units to record their locations during these 15 weeks, and will complete questionnaires about stress levels at specific intervals during the study. - At the end of the study, participants will have the choice of transferring to a community clinic or undergoing an 8-week taper from methadone.
Children born to women who abuse drugs have a high risk of being born with birth defects and developmental problems. Methadone is a drug that is commonly used for treating opioid dependence. However, its use by a pregnant woman can cause severe withdrawal symptoms in a newborn because of the prenatal exposure. The purpose of this study is to evaluate the effectiveness of buprenorphine, another drug, versus methadone in reducing withdrawal symptoms in children born to opioid-dependent women.
The purpose of this study is to assess the feasibility, cost, and effectiveness of a model of care designed to integrate buprenorphine treatment for opioid dependence into the HIV primary care clinics at the UCSF Positive Health Program.
The primary purpose of the study is to determine if the central feature of the Therapeutic Workplace, the abstinence reinforcement contingency, is critical to initiate cocaine abstinence in injection drug using methadone patients who use cocaine consistently during methadone treatment. All subjects initially will be invited to attend the Therapeutic Workplace for an initial period, but abstinence will not be required to work during that time. During this initial period, vouchers will be contingent only on workplace attendance and performance on the training programs. Subjects (n=70) who attend the workplace consistently during the first 4 weeks of treatment, but who continue to use cocaine will be randomly assigned to a Work Only or an Abstinence Plus Work group. Subjects in the Work Only group will continue to be able to work independent of their urinalysis results. However, subjects in the Abstinence Plus Work group will be required to provide urine samples that show evidence of recent cocaine abstinence. Subjects in both groups will be invited to stay in the workplace for 6 months. We expect the subjects in the Abstinence and Work group will achieve higher rates of abstinence than the subjects in the Work Only group. This result would show that the abstinence reinforcement contingency (i.e., the requirement to provide cocaine-free urine samples to work and earn vouchers) is important in the initiation of abstinence in the study population.
This study is designed to test whether a telephone call-in program is a feasible way to collect mood and drug-related information in individuals enrolled in a methadone maintenance program.
Cocaine is an extremely addictive stimulant drug that directly affects the brain. It is used in several different forms and can be snorted, smoked, or injected to achieve the desired effect. Cocaine users are at risk for many health problems, both directly and indirectly related to the effects of cocaine. Disulfiram, a drug used to treat chronic alcoholism, may be effective in reducing cocaine use. This study will evaluate the effectiveness of three different doses of disulfiram in treating cocaine dependence in opioid- and cocaine-dependent individuals maintained on methadone.
Heroin addiction is a growing problem in Russia; individuals who enter heroin addiction treatment often relapse. Therefore, effective heroin addiction treatments are necessary to prevent relapse. The purpose of this study is to compare oral naltrexone with a naltrexone implant that provides opioid blockade for two months in preventing relapse to heroin addiction in St. Petersburg, Russia.
